From time to time, there are always some customers complaining about the width difference for the same solid wood floor product that the difference can be up to 1-2 mm. This is not easy to justify since NWFA standard only allows +- 0.005″ for 3-1\/4″ or less stripe or +- 0.008″ for planks wider than 3-1\/4″. But is the NWFA standard realistic?\u00a0<\/p>\n
Today I came across an article with a good answer. Basically this article points out a very good fact that each plank, even in the same carton, may come with different moisture content (MC) level. According to NWFA standard, a 6-10%\u00a0 MC level variation is allowed for the fresh manufatured product. So because the 4% MC difference is allowed, we can readly get the width difference allowance using the following formula:<\/p>\n
% moisture change x width x C ( <\/span>C is the dimensional change coefficient )<\/span><\/p>\n From the above formula, we can get the width difference between 3-1\/4″ wide plank can be 1.2mm and 1.8mm for 5″ plank, which is very normal in real life.<\/span><\/p>\n So we may want to let the customer know this before they purchase the wood floor that no surprise afterwards.<\/span><\/p>\n <\/p>\n Reference is here: https:\/\/www.woodfloorbusiness.com\/wood-flooring\/prefinished\/article\/15125426\/it-varies-we-cant-expect-solid-prefinished-wood-floor-widths-to-be-perfect#:~:text=A%20newly%20educated%20expert%20may%20quote%20the%20new%20NWFA%20standard%3A&text=for%20flooring%20with%20an%20actual,is%20%2B%20or%20%2D%200.005%E2%80%9D.&text=for%20flooring%20greater%20than%203,is%20%2B%20or%20%2D%200.008%E2%80%9D.<\/span><\/p>\n <\/span><\/p>\n <\/span><\/p>\n <\/span><\/p>\n <\/span><\/p>\n <\/span><\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":" From time to time, there are always some customers complaining about the width difference for the same solid wood floor product that the difference can be up to 1-2 mm.
